<pre>`string_view` literal operators should have 'noexcept' specifier according to
the C++17 standard:
<a href="https://github.com/cplusplus/draft/blob/4ba4e9c2c04b7680ac2a56b65c241ec10c427c3f/source/strings.tex#L4611">https://github.com/cplusplus/draft/blob/4ba4e9c2c04b7680ac2a56b65c241ec10c427c3f/source/strings.tex#L4611</a>
Currently libc++ implements the literal operators via
`basic_string_view<_charT>(const _charT*, size_t)` ctor which are not specified
as `noexcept` according to the same standard.
